FIGURE 5. Parametric images of Logan DVR using 90 min of emission data and either arterial data (ART90; top) or CER tissue (CER90; bottom) as input. Shown are a young control (C-4), a control with detectable amyloid deposition in FRC (C-2), an amyloid-negative MCI subject (M-2), an MCI subject with intermediate levels of PIB retention (M-10), an amyloid-positive MCI subject with levels of PIB retention characteristic of AD (M-4), and a typical AD subject (A-2).
